*Application October 28, 1941, Serial No. 416,784 Claims. (01. 12639) This invention relates to improvements in gas ranges and has for a main object the improvement of the external appearances of ranges, the

in gas ranges of improved wall construction, in'- cluding panels formed of composite pressed boards which are fireproof, have admirable in-- sulating qualities, and the outer surfaces of which are capable of taking a fine finish.

A further object of the invention is the provision in gas ranges of composite panels which not only provide insulation, but also carry the desired finishes on the outer surfaces thereof.

A further object of the invention is the provision in a. gas range of the sky-scraper type. of a recessed or stepped-in break in the front of said range at the base thereof, permitting the user to stand closer to the range when desired.

Other objects of the invention will be apparent to those skilled in the art.

Referring now to the drawing- Figure 1 is an external perspective view of a range made according to the invention;

Figure 2 is a sectional elevation of the range shown in Figure 1 showing structural details thereof;

Figure 3 is a sectional view taken along the line 3- -3 of Figure 2;

Figure 4 is an enlarged sectional view of a por- 7 tion of thedevice shown in Figure 2; and

Figure 5 is a fragmentary view in section showing a wall structure of the prior art. I

The range, generally designated by the numeral I0, is tall and is generally of rectangular cross section. At the top of the range is the burner. section Ii, which is provided with a removable cover i2. This cover may either be hinged to the range at the back near the splashplate [8, or it may be removable. The burners I! are controlled by valves l5 and are positioned in the burner compartment l8. Beneath the burner compartment is an oven ll which is separated from the burner compartment by an 4 insulated wall it.

In the side walls of the oven are aligned proiections 19 upon which suitable shelves 2!! may be positioned. Beneath the oven is a broiler compartment 2! which is separated from the oven proper by the plate 22. Below the plate 22 is a burner 23 which supplies heat for both the broiler and the oven.

The burner 33 is controlled by an automatic valve. 25. The projections 25 in the side walls of the broiler chamber are provided for supporting a pan 28. The projections 23 are spaced apart from each, other, thereby permitting the Mn 28 to be positioned within the broiler.

A door 21 is hingedly mounted on the range for giving access to the oven, and this door is provided with a suitable handle 28. A second door 29 is hingedly mounted on the range for access to the broiler, and this door is likewise provided with a handle 30.

The left side 3| of the range has its lower front corner cut awayto form a recess 32 therein. The right side 33 of the range has its front comer cut away to form a recess 34 therein. These recesses are in alignment with each other and are covered by a kick-plate 35 which is substantially parallel with the front of the range but spaced apart rearwardly therefrom. This permits the user of the range to step up closer to the front of the range, which is advantageous particularly when using the rear burners.

Figure 3 is a sectional view taken along the line 3-3 of Figure 2, and shows the angle iron frame and the method of securing the walls thereto. The side and back walls, and also the doors, are provided with insulations.

Referring now to Figure 4, which is an enlarged fragmentary sectional elevation, showing details of construction. For example, the bottom of the burner compartment I6 is provided with a sheet metal lining 36, and the upper surface of the oven compartment is also bounded with a sheet metal lining 31. Between the linings 36 and 31, suitable insulation 38 is provided.

Within the compartment [6, the lining 36' extends upwardly, and within the oven compartment the lining 31 extends downwardly, and carries the aligned projection l9. The lining 31 extends downwardly in the broiler compartment and has formed integral therewith the projections 25. I

The outer wall 40 is preferably formed-0f asbestos or other heat resistant material or compound which have been compressed and the outer surface of which at least is very hard. Suitable insulation 39 is provided in the space between the outer wall and the linings 36 and 31.

The insulations 38 and 39 may be formed of loose insulating material which is packed in, or it may be formed of pressed material and put in in sheets. Another arrangement contemplates the use of a composite material the outer surface of which is provided with a hard finish and the remainder of which is less hard and particularly adapted for insulating purposes.

In the latter instance the labor of constructing the is materially reduced because in app rins th sheets of material, the proportion thereof adapted as an insulator is automatically positioned in place when the sheet is applied, and the outer wall with its hard surface is particularly adapted for receiving the finish. In some instances it has been found advantageous to appl the finish to the hard surfaces of the sheets before the sheets are assembled into the range. I have found that almost any type of finish may be applied to the outer surfaces of these sheets in as many cost: as desired, and when a particularly fine finish is desired the preceding coat may be rubbedsoastoenhancethefinslfinish.

In Figure 5 is shown a fragmentary view illustrating the method of finishing ranges of the prior art. wherein packing or insulation ll is positioned between the inner middle wall 44 and the outer middle wall 45 on the sides, and between the upper middle wall ll, 8. break strip 41 being provided between the inwardly turned edges of the top wall 46 and the side 45. V

The herein described method has distinct advantages over this type of construction in that the thin sheets of metal 45 and 40-, after being finished with a vitreous enamel are subject quite often to having the enamel flake off in places while the material is being handled, and quite often the,

flaking-of! occurs in the most conspicuous place. With my new type of construction herein shown and described. flnishesequal to the vitreous finish can be obtained and there is no chance for this finish to flake off.

Another important advantage with my new form of construction is that the weight of the finished range is substantially reduced, thereby making it more easily handled.

Further, it must be understood that my new form of construction, although described in connection with a skyscraper type of range; this type of construction is equally applicable to tabletop forms of ranges, and in cases where the ex- What is claimed is:
